INSTRUCTIONS FOR MARKING BIRDS. 



1. It is most important to note down the number of the ring and the 



species of bird immediately you have marked it, and to enter up 

 the Schedule without delay. The number of any ring lost or 

 broken must be noted. 



2. Any birds that can be caught should be marked, but the easiest to 



obtain are nestlings just before they fly. 



3. Do not mark any bird unless you are quite certain of the species. 



4. Do not mark any injured bird, nor any bird which has been in 



captivity. 



5. The rings are made in three sizes : — the largest size is suitable for 



Peewits, Gulls, Rooks, etc. ; the medium size for Starlings, 

 Thrushes, Snipe, etc. ; the smallest size for Warblers, Tits, etc. 



6. To fix the ring : — Hold the bird with its back upwards and its legs 



away from you in one hand, and with the forefinger and thumb 

 of the same hand hold one of the legs at the ankle joint (some- 

 times called the knee). With the other hand slip the ring on 

 to the tarsus, just above the foot, and, with the finger and 

 thumb or a pair of pliers, press the ends of the ring together 

 so that they just meet. See that the ring cannot slip off the 

 foot before you release the bird. 



7. Schedules, when complete (i.e., when 20 birds have been marked) 



or when partly filled if no more birds are likely to be marked 

 for some time, should be sent immediately to the Editors of 

 British Birds, 326, High Holborn, London. Requests for 

 additional rings (the sizes wanted should be stated) and 

 schedules should be addressed the same, and it is requested that 

 all communications be marked " M " upon the envelope. 



8. Full particulars should be sent in of all marked birds recovered, 



even if they are recovered in the district in which they were 

 marked. 



9. If a ring is recovered it must not be used a second time or confusion 



will arise.
